A fastening assembly includes a mounting cylinder frame, a movable part and a turnover part, the mounting cylinder frame is provided with a first vertical beam and a transmission rod, the mounting cylinder is provided with a butting block at the top of the first vertical beam, the transmission rod passes through the butting block, the side wall of the first vertical beam is provided with a bulge, the movable part is connected with the transmission rod, and the turnover part is arranged on the first vertical beam and rotationally connected with the movable part. The turnover part is butted with the bulge, the turnover part is located between the butting block and the movable part, and has a vertical state and a horizontal state. The transmission rod is used to drive the turnover part to switch between the horizontal state or the vertical state.

An access mat system and method of assembly is provided. An access mat system having a plurality of wooden layers arranged in a stacked orientation. A plurality of paired angled through holes are bored in each plank of the plurality of wooden layers except for a topmost layer of the plurality of wooden layers. A plurality of paired angled blind holes are bored in each plank of the topmost layer. The plurality of paired angled blind holes are positioned to correspond to the plurality of paired angled through holes. A plurality of biodegradable fasteners are inserted into the plurality of paired angled blind holes and the pair angled through holes, wherein the paired angled blind holes are bored in opposing orientations and do not touch within the plank and wherein the paired angled through holes are bored in opposing orientations and do not touch within the plank.

A self-drilling expanding anchor bolt, including a drill bit for drilling, an anchor rod connected to the drill bit, and an expanding sleeve surrounding the anchor rod, the anchor rod having an expansion cone at a first end adjoining the drill bit, having a neck region behind and contiguous with the expansion cone, and having a threaded segment at a second end of the neck region remote from the drill bit, wherein the expansion cone expands the expanding sleeve in a radial direction when the expansion cone is pulled into the expanding sleeve; a transition part is provided between the drill bit and the expansion cone of the anchor rod, the maximum diameter of the transition part being smaller than the hole diameter of a drilled hole formed by the drill bit.

A setting device for a self-drilling anchor bolt of the present invention includes: a drive shaft, one end thereof having a shank for connecting to an impact tool, and another end being a setting part for pushing the self-drilling anchor bolt axially; a coupling, partially surrounding the drive shaft along an axis, and being supported on the drive shaft in such a way as to be incapable of relative rotation while being axially moveable at least locally; and a releasable locking component, disposed between the drive shaft and the coupling; in a locked position, the locking component is coupled to an extremity of an anchor rod such that the anchor rod is fed axially with rotational striking into a receiving material, and in a released position, the drive shaft strikes a sleeve to advance axially along the anchor rod and expand at an expansion part.

A purpose of the present disclosure is to provide a clip including a grommet and a pin, which does not degrade design quality and allows the clip to be removed easily from members to be attached without causing damage. The grommet is configured to be inserted into attachment holes of the members to be attached, and includes a grommet hole into which a pin is to be inserted. Depending on an insertion position of the pin relative to the grommet, the grommet undergoes elastic deformation to allow the members to be attached to each other or detached from each other. A flange portion of the grommet has an engagement hole so that the clip can be removed from the members by engaging a tool with the engagement hole.

A wall magnet anchor system is used to install magnetic anchors in wall material that can be used to magnetically hold an object to the wall, thereby avoiding the need to a conventional hook that protrudes from the surface of the wall. The anchor can include a helical thread to hold the anchor in the wall. An installation tool includes a cutting features at one end for cutting a hole in a wall to receive an anchor, and an installation feature that engages the anchor and allows a user to drive the anchor, through rotation, into the hole cut by the cutting features.
